Chapter XXVII.--All Need Baptism.
"Therefore approach, be ye righteous or unrighteous. For if you are righteous, baptism alone is lacking in order to salvation. But if you are unrighteous, come to be baptized for the remission of the sins formerly committed in ignorance. And to the unrighteous man it remains that his well-doing after baptism be according to the proportion of his previous impiety. Wherefore, be ye righteous or unrighteous, hasten to be born to God, because delay brings danger, on account of the fore-appointment of death being unrevealed; and show by well-doing your likeness to the Father, who begetteth you of water. As a lover of truth, honour the true God as your Father. But His honour is that you live as He, being righteous, would have you live. And the will of the righteous One is that you do no wrong. But wrong is murder, hatred, envy, and such like; and of these there are many forms.
Chapter XXVIII.--Purification.
"However, it is necessary to add something to these things which has not community with man, but is peculiar to the worship of God. I mean purification, not approaching to a man's own wife when she is in separation, for so the law of God commands. But what? If purity be not added to the service of God, you would roll pleasantly like the dung-flies. Wherefore as man, having something more than the irrational animals, namely, rationality, purify your hearts from evil by heavenly reasoning, and wash your bodies in the bath. For purification according to the truth is not that the purity of the body precedes purification after the heart, but that purity follows goodness. For our Teacher also, dealing with certain of the Pharisees and Scribes among us, who are separated, and as Scribes know the matters of the law more than others, still He reproved them as hypocrites, because they cleansed only the things that appear to men, but omitted purity of heart and the things seen by God alone.
Chapter XIX.--Outward and Inward Purity.
"Therefore He made use of this memorable expression, speaking the truth with respect to the hypocrites of them, not with respect to all. For to some He said that obedience was to be rendered, because they were entrusted with the chair of Moses. However, to the hypocrites he said, Woe to you, Scribes and Pharisees, hypocrites, for ye make clean the outside of the cup and the platter, but the inside is full of filth. Thou blind Pharisee, cleanse first the inside of the cup and the platter, that their outsides may be clean also.' And truly: for when the mind is enlightened by knowledge, the disciple is able to be good, and thereupon purity follows; for from the understanding within a good care of the body without is produced. As from negligence with respect to the body, care of the understanding cannot be produced, so the pure man can purify both that which is without and that which is within. And he who, purifying the things without, does it looking to the praise of men, and by the praise of those who look on, he has nothing from God.
Chapter XXX.--"Whatsoever Things are Pure."
"But who is there to whom it is not manifest that it is better not to have intercourse with a woman in her separation, but purified and washed. And also after copulation it is proper to wash. But if you grudge to do this, recall to mind how you followed after the parts of purity when you served senseless idols; and be ashamed that now, when it is necessary to attain, I say not more, but to attain the one and whole of purity, you are more slothful. Consider, therefore, Him who made you, and you will understand who He is that casts upon you this sluggishness with respect to purity.
Chapter XXXI.--"What Do Ye More Than Others?"
"But some one of you will say, Must we then do whatsoever things we did while we were idolaters? I say to you, Not all things; but whatsoever you did well, you must do now, and more: for whatsoever is well done in error hangs upon truth, as if anything be ill done in the truth it is from error. Receive, therefore, from all quarters the things that are your own, and not those that are another's, and do not say, If those who are in error do anything well we are not bound to do it. For, on this principle, if any one who worships idols do not commit murder, we ought to commit murder, because he who is in error does not commit it.
